Reaction Steps

In the first step, 4,4'-dinitro-2-biphenylamine is reacted with benzoyl chloride in the presence of 4-dimethylamine pyridine in N-methyl-2-pyrrolidinone (NMP) to give 2-(N-benzoylimino)-4,4'-dinitrobiphenyl. The hydrogenation of the latter in N,N-dimethylacetamide (DMAc) at room temperature with 10% Pd/C as a catalyst provides the desired 2-(N-benzoylimino)-4,4'-diaminobiphenyl.
